Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The hard disk read-write protection method provided in this embodiment can be applied to the application environment shown in fig. 1, where a client communicates with a server. The client includes, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server can be implemented by an independent server or a server cluster composed of a plurality of servers.
In an embodiment, as shown in fig. 2, a hard disk read/write protection method is provided, which is described by taking the method as an example for being applied to the client in fig. 1, and includes the following steps S10-S30.
S10, detecting the environment vibration signal of the hard magnetic disk in a specified time period through a sensor; the sensor is disposed within a specified range of the hard disk and changes in position as the position of the hard disk changes.
Understandably, hard disks, also known as hard disks, are short for hard disk storage. A hard disk is a disk memory that utilizes magnetic recording technology to provide data access on a disk having a magnetic surface that rotates at high speeds. The sensor refers to a sensor for detecting an environmental vibration signal. Here, the sensor may refer to a light sensor, and the ambient vibration signal may be a light signal. When the hard magnetic disk is severely vibrated or falls into water, the refractive index of the peripheral medium is changed, and the optical sensor can detect the change to obtain an environmental vibration signal.
The sensor can be disposed within a specified range of the hard disk to facilitate accurate detection of the environmental vibration signal of the hard disk. The specified range can be set according to actual needs. For example, the specified range may be within 10 cm. The position of the sensor changes with the position of the hard disk, and the position of the sensor changes. In the first case, the sensor may be mounted on the motherboard of the mobile computer device together with the hard disk, the motherboard vibrating, the sensor vibrating together with the hard disk. The other is that the sensor is arranged in a movable device, a movable part is arranged in the movable device, the movable device and the hard disk vibrate together, and the movable part vibrates along with the movable part. In the second case, a movable member having a vibration characteristic correlated with that of a head arm of a hard disk is provided in addition to the optical sensor in the movable device. When the sensor detects the vibration of the movable member, the vibration of the hard disk can be estimated based on the vibration.
The specified time period can be set according to actual needs. In an example, the specified time period may be 5 s.
And S20, processing the environment vibration signal according to a preset analysis algorithm to generate a vibration analysis result.
Understandably, since the environmental vibration signal is an optical signal, specifically, a resonance peak wavelength, it needs to be converted into a vibration analysis result that can reflect the vibration magnitude. In the preset analysis algorithm, when the hard disk vibrates violently or falls into water, the refractive index of the peripheral medium changes, and the optical sensor detects the shift of the wavelength of the resonance peak. Wherein, the change quantity (delta lambda) of the resonance peak wavelength and the change quantity (delta n) of the refractive index of the external medium have the following relationship:
wherein N iseffIs the effective refractive index of the mode in the waveguide, n is the refractive index of the external environment substance, and λ is the wavelength of the incident light. The change quantity (delta n) of the refractive index of the external substance can be measured by measuring the change quantity (delta lambda) of the resonance peak wavelength,the change information of the refractive index, the concentration and the like of the measured substance is obtained, and then the vibration analysis result can be obtained. In one example, the vibration analysis results may be expressed in terms of peak wavelength shift rates.
And S30, when the vibration analysis result meets the preset protection condition, sending a protection control signal to enable the hard magnetic disk to be in a vibration protection state according to the protection control signal.
Understandably, the preset protection condition can be set according to actual needs. When the preset protection condition is not met, the vibration of the hard magnetic disk is very small, and the normal work of the hard magnetic disk cannot be influenced. When the preset protection condition is met, the hard magnetic disk has larger vibration, and the hard magnetic disk is easily damaged. The protection control signal is a signal for suspending the process of the hard disk read/write operation temporarily. When the hard magnetic disk is in the vibration protection state, the hard magnetic disk stops all the read-write operations to the hard magnetic disk data. At this time, the head arm of the hard disk is located outside the disk read/write area, and even if the hard disk vibrates violently, the head will not damage the disk area.
In steps S10-S30, detecting an environmental vibration signal of the hard disk in a specified time period through a sensor; the sensor is arranged in the designated range of the hard magnetic disk, and changes in position along with the change in position of the hard magnetic disk, and here, the collected environmental vibration signal can be used for judging the vibration of the hard magnetic disk. And processing the environment vibration signal according to a preset analytical algorithm to generate a vibration analysis result, wherein the obtained vibration analysis result can be used for determining the vibration amplitude of the hard disk. And when the vibration analysis result meets a preset protection condition, sending a protection control signal to enable the hard magnetic disk to be in a vibration protection state according to the protection control signal, wherein the hard magnetic disk is protected by changing the working state of the hard magnetic disk. The hard disk read-write protection method provided by the embodiment can reduce the damage of vibration to the hard disk.
Optionally, the sensor includes an optical waveguide sensor, and the ambient vibration signal includes a plurality of resonance peak wavelengths;
step S10, detecting the environment vibration signal of the hard magnetic disk in the appointed time period by the sensor; the sensor is arranged in a specified range of the hard magnetic disk, and changes in position along with the change in position of the hard magnetic disk, and comprises:
s101, sending an electrifying signal to the optical waveguide sensor; the optical waveguide sensor is arranged at the outer edge of the hard magnetic disk or arranged inside the movable device;
s102, enabling the optical waveguide sensor to be in a working state according to the electrifying signal;
s103, when the optical waveguide sensor is in a working state, acquiring the resonant peak wavelength of incident light through the optical waveguide sensor according to a preset sampling frequency.
Understandably, the sensor may be an optical waveguide sensor. An optical waveguide sensor is a sensor that can measure the wavelength of the resonant peak of incident light. The optical waveguide sensor can be disposed inside the mobile computing device at an outer edge of the hard disk (in one example, meaning that the distance from the outer edge of the hard disk is less than a specified distance, which can be 2 cm). The ambient vibration signal includes a number of resonant peak wavelengths. Specifically, the plurality of resonant peak wavelengths refers to a group of data collected at a preset sampling frequency within a specified time period. For example, if the specified time period is 5s and the preset sampling frequency is 50Hz, 250 resonance peak wavelengths can be obtained.
An energizing signal can be sent to the optical waveguide sensor to place the optical waveguide sensor in an operational state. At this time, the optical waveguide sensor acquires the resonance peak wavelength of the incident light at a preset sampling frequency. The preset sampling frequency can be set according to actual needs, and can be 50 Hz. If the vibration of the hard disk does not need to be monitored, the energizing signal is not sent to the optical waveguide sensor, and the optical waveguide sensor is in a dormant state. The incident light may be a light beam that is irradiated on the optical waveguide sensor after the ambient light passes through the incident light path.
The embodiment installs the optical waveguide sensor inside portable computing device, can not additionally increase portable computing device's volume, also can not occupy portable computing device's usb interface, and the transformation cost is low, can effectively reduce the damage of vibration to the hard disk.
Optionally, the sensor includes an optical waveguide sensor, and the ambient vibration signal includes a plurality of resonance peak wavelengths;
step S10, detecting the environment vibration signal of the hard magnetic disk in the appointed time period by the sensor; the sensor is arranged in a specified range of the hard magnetic disk, and changes in position along with the change in position of the hard magnetic disk, and comprises:
s104, sending an electrifying signal to an optical waveguide sensor arranged in the movable device;
s105, enabling the optical waveguide sensor to be in a working state according to the electrifying signal;
and S106, when the optical waveguide sensor is in a working state, acquiring the resonant peak wavelength of the incident light through the optical waveguide sensor according to a preset sampling frequency.
Understandably, the sensor may be an optical waveguide sensor. An optical waveguide sensor is a sensor that can measure the wavelength of the resonant peak of incident light. The optical waveguide sensor may be arranged inside the movable device. The ambient vibration signal includes a number of resonant peak wavelengths. Specifically, the plurality of resonant peak wavelengths refers to a group of data collected at a preset sampling frequency within a specified time period. For example, if the specified time period is 5s and the preset sampling frequency is 50Hz, 250 resonance peak wavelengths can be obtained.
The removable device may be provided with an interface (e.g., usb (Universal Serial Bus)), which may send a power-on signal to the optical waveguide sensor to enable the optical waveguide sensor to be in an operational state when the interface is connected to the interface of the mobile computing device. At this time, the optical waveguide sensor acquires the resonance peak wavelength of the incident light at a preset sampling frequency. The preset sampling frequency can be set according to actual needs, and can be 50 Hz. If the vibration of the hard disk does not need to be monitored, the energizing signal is not sent to the optical waveguide sensor, and the optical waveguide sensor is in a dormant state. The incident light may be a light beam that is irradiated on the optical waveguide sensor after the ambient light passes through the incident light path.
This embodiment sets up the optical waveguide sensor inside mobile device, is connected with portable computing equipment through the usb interface, has very big convenience and flexibility, and plug-and-play can effectively reduce the damage of vibration to the hard disk.
Optionally, step S105, namely, the making the optical waveguide sensor in the working state according to the power-on signal, further includes:
s1051, acquiring the intensity of incident light detected by the optical waveguide sensor;
s1052, judging whether the incident light intensity is within a preset light intensity range;
s1053, if the incident light intensity is out of the preset light intensity range, generating a light path adjusting parameter according to the incident light intensity;
s1054, adjusting the incident light path of the optical waveguide sensor according to the light path adjusting parameters so that the incident light intensity is within a preset light intensity range.
Understandably, the optical waveguide sensor may be provided with an adjustable incident light path. The incident light path is used for adjusting the incident light intensity of the optical waveguide sensor. The incident light path can be provided with optical devices such as a reflection grating, a miniature convergent lens and the like. When the incident light intensity of the optical waveguide sensor is within the preset light intensity range, the optical waveguide sensor has higher sensitivity. Therefore, it is necessary to control the intensity of the incident light of the optical waveguide sensor to be within a preset light intensity range. The preset light intensity range can be set according to actual needs.
If the intensity of the incident light is outside the preset light intensity range, the light path adjusting parameters can be generated according to the intensity of the incident light. For example, if the intensity of the incident light is smaller than the minimum value of the preset light intensity range, a light path adjusting parameter for increasing the light intensity can be generated, so that the intensity of the incident light is increased; if the intensity of the incident light is greater than the maximum value of the preset light intensity range, light path adjusting parameters for reducing the light intensity can be generated, so that the intensity of the incident light is reduced.
The embodiment adjusts the incident light path of the optical waveguide sensor through the light path adjusting parameters, so that the incident light intensity is within a preset light intensity range, and the sensitivity of the optical waveguide sensor is ensured.
Optionally, in step S1052, after the determining whether the light intensity data is within the set light intensity range, the method further includes:
s1055, if the intensity of the incident light is in the set light intensity range, the optical waveguide sensor is judged to enter the working state.
Understandably, if the intensity of the incident light is within the set light intensity range, the optical waveguide sensor is judged to enter the working state, and at the moment, the optical waveguide sensor can measure the environmental vibration signal with high accuracy.
Optionally, the environment vibration signal includes a plurality of resonance peak wavelengths, and the vibration analysis result includes a vibration amplitude;
step S20, namely, the processing the environmental vibration signal according to a preset analytic algorithm to generate a vibration analysis result, including:
s201, determining a peak wavelength shift rate according to the resonance peak wavelength;
s202, searching in a preset wavelength deviation rate-amplitude ratio comparison table according to the peak wavelength deviation rate, and obtaining the vibration amplitude corresponding to the peak wavelength deviation rate.
Understandably, if at time t (t)>1) Resonance peak wavelength of λtThe resonance peak wavelength at the time t-1 is lambdat-1Then the peak wavelength shift rate can be expressed as:
wherein, Δ δ is the peak wavelength shift rate, and T is the time difference between the time T and the time T-1, which is the preset sampling frequency.
The preset wavelength shift ratio-amplitude ratio look-up table may be data obtained based on actual experiments. In the preset wavelength shift rate-amplitude ratio comparison table, a plurality of sets of corresponding relations between the wavelength shift rates and the amplitude ratios are stored. Here, the amplitude ratio may be a ratio between the current amplitude and the maximum amplitude. As shown in fig. 3, the larger the amplitude ratio, the larger the shift amount of the wavelength (the shift of the peak to the right).
Optionally, as shown in fig. 4, the vibration analysis result includes a vibration amplitude, and the protection control signal includes a read/write suspension signal; when a magnetic head 03 of the hard magnetic disk 01 is positioned outside a magnetic disk read-write area, the hard magnetic disk 01 is in a vibration protection state;
step S30, namely, when the vibration analysis result satisfies a preset protection condition, sending a protection control signal to make the hard disk 01 in a vibration protection state according to the protection control signal, including:
s301, when the vibration amplitude is larger than or equal to a preset amplitude threshold value, judging that the vibration analysis result meets a preset protection condition, and triggering a protection control signal;
s302, sending the protection control signal to a hard disk 01 controller, so that the hard disk 01 controller controls a magnetic head 03 to leave a magnetic disk read-write area through a magnetic head arm 02.
Understandably, the preset amplitude threshold can be set according to actual needs, such as 5%. The protection control signal is a signal for suspending the process of the read/write operation of the hard disk 01 temporarily and finally. Thus, upon receiving the protection control signal, the hard disk 01 controller lifts the head arm 02, and causes the head arm 02 to rotate with the head 03, thereby moving the head 03 away from the disk read/write area (disk area in fig. 4).
When the hard disk 01 is in the vibration protection state, the hard disk 01 stops all reading and writing operations of the hard disk 01 data. At this time, the head arm 02 of the hard disk 01 is located outside the disk read/write area, and the magnetic head 03 does not damage the disk read/write area even if the hard disk 01 vibrates violently.
Optionally, after step S30, that is, after the vibration analysis result meets a preset protection condition, sending a protection control signal to make the hard magnetic disk in a vibration protection state according to the protection control signal, including:
s40, obtaining the read-write mode of the hard magnetic disk, and determining the protection period of the hard magnetic disk according to the read-write mode;
and S50, when the duration time that the vibration analysis result does not meet the preset protection condition is longer than the protection period, sending a protection releasing signal to release the vibration protection state of the hard magnetic disk according to the protection releasing signal.
Understandably, the read-write mode and the protection period can be set according to actual needs. For example, the read/write modes that can be divided based on the operation type include: office mode, entertainment mode, etc.; the read-write modes which can be divided based on the road surface type comprise: mountain road mode, country road mode, etc. The protection period can be set according to the vibration characteristics in a certain read-write mode. In some examples, the guard period may be set to 10s to 100 s. One read-write mode corresponds to at least one protection period. In some cases, in a certain read-write mode, there are multiple protection cycles corresponding to the environment variables. Here, the environment variables include, but are not limited to, vehicle speed, geographical location. And if the current environment variable cannot be acquired, using the default protection period in the read-write mode.
The duration that the vibration analysis result does not satisfy the preset protection condition is longer than the protection period, that is, the duration that the vibration amplitude of the hard disk is smaller than the preset amplitude threshold is longer than the protection period, which indicates that the current environment vibration of the hard disk is smaller. Here, a release protection signal is issued, and the hard disk is released from the vibration protection state in response to the release protection signal. After the hard disk is released from the vibration protection state, the read-write operation can be performed.
The embodiment is based on the protection period set by the read-write mode, combines the vibration characteristic under the read-write mode, can realize intelligent opening and closing of the vibration protection state, and meets the requirements of hard disk data reading and writing while ensuring the safety of the hard disk.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
